This over-the-sink colander is designed to expand from 13.5 inches to 18.7 inches, allowing it to fit securely across most standard kitchen sinks. The adjustable arms rest on the sink edges, keeping the colander elevated for hands-free draining and rinsing. Ideal for washing fruits, vegetables, pasta, or grains, the perforated base ensures efficient water drainage while keeping food contained. Its space-saving design makes it easy to store when not in use and practical for everyday kitchen prep tasks.
